Good deal, lookin forward to it. 300 blackout did interest me a little, but only because its such a,custom load. The cutting down and reforming of .223 cases interests my inner metallurgy. But ive got enough rounds to load for now. My original intention of loading exclusively for 22-250 is quickly being pushed aside for the .223, but I do have 40 rounds for it loaded ready to test when I get a long clear afternoon. The benefit to that is you can use same projectiles as .223. My pops is excited for me to start loading for .308, since he has one he predator hunts with. Gonna try and make up some medium sized game loads that work equally well in both our rifles. I'm thinkin Nosler bonded. Somethin that will have distant reach, with good terminal ballistics. Also want to work with some good bonded bullets in .224 diameter. Definitely not for plinking though. From here on out my .223 reloads are exclusively for the bull barrel upper. I'll burn factory ammo through the carbine. And save the brass.
